Description

Technical Field

[0001] This application belongs to the field of air purifier technology, and more specifically, relates to an air purifier. Background Technology

[0002] Air purifiers are home appliances that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness. Therefore, air purifiers are equipped with a variety of sensors to detect air pollutants.

[0003] To ensure the accuracy of sensor detection, existing air purifiers require a certain distance between different sensors. Each sensor can only detect its own corresponding area and cannot accurately display the current air quality in the area. For example, temperature and humidity sensors need to be far away from other sensors and can only detect the air in a small area in front of them. They cannot work together with other sensors to accurately reflect the current air conditions in the area.

[0004] Sensor detection and installation require the design of independent sensor brackets. Different sensors require different sensor brackets, which will occupy the space of the whole machine and increase the cost of installation and parts. The connection of the air duct is not completely sealed, which leads to the leakage of airflow from the air duct, thereby affecting the accuracy of the sensor. Utility Model Content

[0041] Please refer to Figures 1 to 5 , the air purifier provided by the embodiments of the present application will be described. The air purifier comprises a shell 106 and a sensor support 101; as shown in Figure 5 , the shell 106 is provided with a plurality of ventilation holes 161, the sensor support 101 is installed in the shell 106 and is arranged towards the ventilation holes 161; as shown in Figure 4 , the sensor support 101 is provided with a surrounding bone 111, which divides the sensor support 101 into a plurality of placement areas 112, as shown in Figure 3 , the plurality of placement areas 112 are respectively provided with a PM2.5 sensor 102, a temperature and humidity sensor 103, a TVOC sensor 104 and a carbon dioxide sensor 105.

[0042] Compared with the prior art, in the application, a plurality of surrounding bones 111 are arranged on the sensor support 101 to form a placing area 112, so that the PM2.5 sensor 102, the temperature and humidity sensor 103, the TVOC sensor 104 and the carbon dioxide sensor 105 are concentrated in the same area, the sensors work in linkage, the current air condition of the area can be more accurately reflected to the consumer, the detection accuracy of the air purifier is improved, meanwhile, the normal work of the sensors is ensured while the installation space of the whole machine is saved and the size of the whole machine is reduced; the plurality of sensor mounting structures are replaced by the whole sensor support 101, the number of parts is reduced and the cost of the whole machine is saved; the sensors are concentrated on the sensor support 101, the connection lines of the sensors can be uniformly routed, the installation steps can be simplified and the production efficiency is improved.

[0043] In the embodiment, the shell 106 not only provides protection for the sensors on the sensor support 101, but also plays a role in fixing the sensor support 101, so as to ensure the stability and accuracy of the sensor support 101 in the air purifier.

[0044] It can be understood that the plurality of ventilation holes 161 can ensure the air circulation to ensure that the sensors can accurately detect various components in the air.

[0045] In the embodiment, the PM2.5 sensor 102, the temperature and humidity sensor 103, the TVOC sensor 104 and the carbon dioxide sensor 105 are arranged in sequence, the PM2.5 sensor 102 generates airflow in a small area when working, which drives the surrounding air to flow in a small range of the temperature and humidity sensor 103, the TVOC sensor 104 and the carbon dioxide sensor 105, so that all the sensors detect the gas in the same area, thereby accurately detecting the air.

[0046] In the embodiment, the working principle of the PM2.5 sensor 102 is to use laser scattering technology to calculate the concentration of particulate matter by measuring the scattering degree of particulate matter in the air. The temperature and humidity sensor 103 measures the temperature and humidity changes in the air and uses the capacitive or thermistor principle to detect the environmental temperature and humidity. The TVOC sensor 104 detects the concentration of volatile organic compounds (VOCs) in the air, usually using semiconductor or PID (photoionization detector) technology. The carbon dioxide sensor 105 detects the concentration of carbon dioxide in the air by infrared absorption principle. The cooperative work of these sensors enables the purifier to monitor and analyze indoor air quality in real time and provide accurate environmental data for users.

[0047] In this embodiment, three surrounding bones 111 can be provided to divide the sensor support 101 into four placement areas 112, and each placement area 112 corresponds to placing one sensor. It can be understood that the shape of each surrounding bone 111 is not exactly the same, and correspondingly, the shape of each placement area 112 is also not exactly the same. The shape of the surrounding bone 111 and the placement area 112 matches the shape of the corresponding sensor, so as to better fix the corresponding sensor. It can be understood that the placement area 112 is provided with a relief hole matching the shape of the sensor. It is worth noting that the sensor referred to in this embodiment refers to any one of the PM2.5 sensor 102, the temperature and humidity sensor 103, the TVOC sensor 104, and the carbon dioxide sensor 105.

[0048] In an embodiment of the present application, the outer surface of the sensor support 101 is arc-shaped, which is matched with the inner surface of the shell 106. In this way, the outside air can directly contact the sensor through the ventilation hole 161 and the relief hole, avoiding the mixing of other air in the shell 106, and improving the detection accuracy.

[0049] Please refer to Figure 6 , the inner surface of the shell 106 is provided with a buckle 162, and the sensor support 101 is clamped on the buckle 162. In this embodiment, by providing the buckle 162, the sensor support 101 can be conveniently fixed on the shell 106, and the sensor support 101 can be conveniently disassembled and replaced, improving the maintenance convenience of the purifier. The buckle 162 can be designed as a simple plug-in structure, or a structure with a locking mechanism to ensure that the sensor support 101 will not be displaced due to vibration or external force during the operation of the purifier.

[0050] In an embodiment of the present application, please refer to Figure 6 , the inner surface of the shell 106 is also provided with a positioning rib 163, which is used for limiting the length or width direction of the sensor support 101.

[0051] In this embodiment, by providing the positioning rib 163, the accurate position of the sensor support 101 during installation can be ensured, and the deviation of the sensor position caused by improper installation is avoided, so as to affect the detection accuracy. The positioning rib 163 can be single or multiple, which is determined according to the width of the sensor support 101 and the size of the internal space of the shell 106. In addition, the positioning rib 163 can also play a role in strengthening the structure of the shell 106, improving the overall stability and durability. In actual application, the shape and size of the positioning rib 163 can be adjusted according to the specific size of the sensor support 101 and the design of the shell 106, so as to achieve the best matching effect.

[0052] In this embodiment, the number of positioning ribs 163 is two, and the two positioning ribs 163 are located on both sides of the length direction of the sensor bracket 101 to limit the movement of the sensor bracket 101 in the length direction.

[0053] In one embodiment of the present application, please refer to Figure 1 and Figure 2 , the air purifier includes an air duct housing 201 and an air inlet housing 202, the air duct housing 201 is sealingly connected with the air inlet housing 202, the outer shell 106 is covered on the air inlet housing 202, and the outer shell 106 and the air inlet housing 202 have a containing cavity, and the sensor bracket 101 is located in the containing cavity.

[0054] In this embodiment, the design of the air purifier aims to optimize the air flow path and improve the purification efficiency. The sealing connection of the air duct housing 201 and the air inlet housing 202 ensures that the air does not leak when entering the purifier, thereby ensuring the purification effect. The outer shell 106 is covered on the air inlet housing 202, which not only provides additional protection for the air purifier, but also forms a closed containing cavity, so that the sensor bracket 101 can be stably installed therein.

[0055] In addition, the containing cavity formed between the outer shell 106 and the air inlet housing 202 provides a relatively independent space for the sensor bracket 101, avoiding direct exposure of the sensor to other parts of the purifier, such as motors or fans, which may interfere with the components, thereby ensuring the normal work and detection accuracy of the sensor. The structural design and layout of the air purifier consider the principle of aerodynamics, ensuring that the air can smoothly flow to the filter system of the purifier after being detected by the sensor, further improving the overall performance of the purifier.

[0056] In one embodiment of the present application, please refer to Figure 2 and Figure 7 , the upper end of the air duct housing 201 is provided with a stop groove 211, and the lower end of the air inlet housing 202 is clamped in the stop groove 211. Alternatively, the lower end of the air inlet housing 202 is provided with a stop groove 211, and the upper end of the air duct housing 201 is clamped in the stop groove 211.

[0057] In this embodiment, the design of the stop groove 211 makes the connection of the air duct housing 201 and the air inlet housing 202 more tight, effectively preventing air leakage at the connection. The shape and size of the stop groove 211 are accurately calculated to ensure that the air duct housing 201 and the air inlet housing 202 can be tightly fitted, and at the same time, it is convenient for installation and disassembly.

[0058] In practical applications, the stop groove 211 can be designed with different materials and structures to adapt to different working environments and requirements. For example, the stop groove 211 can be made of elastic materials to increase the sealing and impact resistance of the connection. In addition, the arrangement of the stop groove 211 can also reduce the vibration of the air purifier inside the purifier, thereby reducing noise and providing a more quiet use environment. Through such design, the air purifier not only improves the performance of the purifier, but also enhances its stability and durability.

[0059] In an embodiment of the present application, referring to Figure 2 , the air purifier further comprises a sealing ring 203 arranged in the stop groove 211.

[0060] In this embodiment, the sealing ring 203 is designed to further ensure the sealing of the connection between the air duct shell 201 and the air inlet shell 202, preventing air leakage. The sealing ring 203 is usually made of soft and elastic materials such as silicone or rubber, which can form a good sealing interface at the connection. During installation, the sealing ring 203 is placed in the stop groove 211, and when the air duct shell 201 is clamped with the air inlet shell 202, the sealing ring 203 is compressed, thereby filling the small gap between the two and ensuring the sealing of air flow. In addition, the use of the sealing ring 203 can also absorb some vibration, reducing the noise generated by the operation of the equipment, providing a more quiet use environment for the user. When designing the sealing ring 203, its temperature resistance, pressure resistance and aging resistance performance need to be considered to ensure that it can continuously provide stable sealing effect during long-term operation of the purifier.

[0061] In an embodiment of the present application, the air duct shell 201 and the air inlet shell 202 are connected by screws.

[0062] In this embodiment, the air duct shell 201 and the air inlet shell 202 are connected by screws, which can achieve quick and firm connection. The use of screws not only simplifies the assembly process, but also improves the reliability of the connection. In practical applications, the size and number of screws can be selected according to the specific structure of the air duct shell 201 and the air inlet shell 202 to ensure the strength and stability of the connection. In addition, the design of screw connection also allows easy disassembly and replacement of the air purifier when needed, facilitating maintenance and repair. In order to further enhance the durability of the connection, the screws can be made of corrosion-resistant materials to adapt to the humid environment that may exist inside the purifier. Through this screw connection method, the air purifier can work more stably, ensuring that the purifier can maintain high purification performance under various use conditions.

[0063] In an embodiment of the present application, the air purifier further comprises a light strip 204, which is arranged on the air duct shell 201 or the air inlet shell 202; the outer wall of the air duct shell 201 or the air inlet shell 202 is provided with a clamping site 212, and the light strip 204 is clamped in the clamping site 212; in this embodiment, the light strip 204 is arranged on the air duct shell 201, and please refer to Figure 2 and Figure 7 for details.

[0064] In this embodiment, the arrangement of the light strip 204 not only increases the aesthetic appearance of the purifier, but also provides practical functions. The light strip 204 can be an LED light strip 204, which indicates the working state of the purifier, such as running, standby or replacing the filter, through different colors or flashing modes. In addition, the light strip 204 can also play the role of auxiliary lighting, so that the user can clearly see the control panel and operation buttons of the purifier in the night or in the environment with relatively dark light. When designing the light strip 204, factors such as brightness, color and energy consumption need to be considered to ensure that the performance of the purifier is not affected while providing sufficient lighting effect and visual prompt.

[0065] In this embodiment, the light strip 204 is arranged on the outer wall of the air duct shell 201, and the airflow generated by the operation of the fan in the air duct shell 201 can carry away the heat generated by the operation of the LED light strip, thereby solving the problem that the accuracy of each sensor is affected by the heating of the light strip 204.

[0066] In an embodiment of the present application, please refer to Figure 2 and Figure 5 for details.

[0067] In this embodiment, by arranging the lampshade 205, the light strip 204 can be protected from dust and moisture, and the lighting effect of the light strip 204 can be enhanced. The lampshade 205 is usually made of transparent or translucent material, which can ensure uniform scattering of light and avoid direct illumination to produce glare. In actual application, the shape and size of the lampshade 205 can be adjusted according to the specific position of the light strip 204 and the overall design of the purifier to achieve the best lighting effect and protection. In addition, the lampshade 205 can be designed as a structure that is easy to disassemble, which facilitates cleaning and replacement of the light strip 204, thereby improving the maintenance convenience of the purifier. Through such design, the lampshade 205 not only enhances the aesthetic appearance of the purifier, but also ensures the stable operation and service life of the light strip 204.

[0068] The above only describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
